We carry models fro both direct connection an cigarette lighter connections. Auto power inverters usually max out at 300 watts for cigarette lighter socket use. Direct Connect is require for loads over 300 watts.

This is not a limit of the auto power inverter, rather it is a limit of the wiring and fusing in your automobile.

We have a number of 300 watt or less units, but the best all around unit for your car is this 1500 Watt True Sine Wave. I like this unit because it will power most, if not all, the loads you would want to use in an auto application.
